MACHINE FOR MAKING INSULATING BATS.

Applicationled *February 23, 1928. Serial 110.256,35).

My present invention relates to the manufacture of sound and heat resisting insulat. ing material of the naturek used for carpet linings and in `bg'uilding construction, the same consisting ingeneral of a soft fibrous interior body and liner sheets applied to one or` both sides thereof, and the invention has for its object to provide a simple and eiiicient machine for rapidly making a .product of this naturel in large quantities, and as a continuous process. The invention also contemplates the provision of means for rendering the material fire resisting.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will hereinafter be more fully described, the novel 'features being pointed out in the claims atthe end of the specification.

In the drawings: v Fig. 1 is aside elevation of a machine constructed in accordance with and illustrating one embodiment of my invention;

forms no ing fully escribed and-'claimed -in a companion a herewlt but I will first briefly describe the The product or insulating material itself art of the present inventiombelication filed by me concurrently general construction thereof-in its preferred form'.

Referrin to`Figs. 2 land 3,'1 indicates a central bo y of soft, heterogeneously arranged felted fibres, formed into a fiat bat. On opposlte sides thereof are applied a pluof theppposite end 1 vNext adjacent thereto are a pair of supports 9 carrying axles 10 upon whlch are su portved above and below the table rolls 11 o? rality of longitudinally extending parallel strips 2 and 3 of strong paper, vor similar material. Corresponding units dn op osite sides are arranged opposite each oty er in pairs, as shown in Fig. 3, and the 4Strips are secured to the bats by sewing them'together, as indicated rat 4. l With respect to some or all of the interior strips 3 a double line of stitching is used as shown, and when .the article is manufactured in great widthsas is contemplated by the Ipresent invention it is cut along longitudinal lines, indicated at 23 running between these double stitches -so that the severed pieces are `strongly secured by atl least one line of stitchlng at both of their edges. This stitching holds the shifting. After the sewing paper iners 5 are applied to the opposite faces, and cemented thereto by the use of a suitable adbat body rmly in place against creeping, or .f

hesive, such as a solution of sodium)` silicate,

asphaltum, glueor other well known cements used in the paper making art. This adhesive l body is indicated at 6 and has the effect not onl of securing-the liner to the strips, but

of lmbedding the stitches 4 therein, so that the ends of each thread passing through the bat is firmly -anchored between the liner and the strip.

Fig. 1 gives the general View of the making machine, and I will first give a general description with reference to that showing in which G'indicates generally a Garnett picker, or familiar type ofIbat making machine, the details of lwhich are of no conseuence to this invention 'and a plication.' t is suiiicient to say that the at fibrous batl issues therefrom in arcontinuou's strip between discharge rollers 7 onto a table 8.

Strip paper suitably spaced to lay the strips 3 at 4the proper interval in a continuous manner upon the traveling bat. These elements -together with the liners labout to be described are drawn through 'the machine by means of a plurality of feed and pressure rolls 12 carried bya frame work 13,- wliich rolls are suitably driven and ma lbey heated or not according to the adheslve and othermabat with the strips thereon .passes y machine 14, which applies vthe stitching 4.2.y lThe 'rlineri 5 similarlypassesover lAfter thel sewing operation a lower hner "strip 5 is drawncfrom a supply roll 15 over suitable guide .rollers and throu h a dope guide rolls v32, 33 and 34 in the order named, the last mentioned two being in the dope box 16.

Fromthence the liner passes up and through. the feed. rolls 12 and becomes attached and pressed to the under side ofthe bat, and the Incase it is desired to impregnate the bat orinner fabric body lwith a fire resisting or a water resisting,material, I prefer to introduce this in a powdered form from a hop- 15 per 18 supported in the frame 13. Any suitable substance may be used, and it is sifted down upon the ex osed surface of the bat from one of the eed rolls 12a, which as shown cooperates with. the mouth of the hopper. During the further -travel of thev structure through the machine this powder is automatically shaken through tov impreg The' upper liner 5a is next applied tothe i uppersurface .in the same manner as that described with respect to the lower liner. It is drawn from a supply roll'19 over suitdable guides'through an upper dope box J20,

where the adhesive is applied by roller 21 asses between the rolls 12. Beyond thisI omt after pass ingsthro'ugh several more' eed and pressure ro thestructure becomes'a finished material. If the machine is a large one and it is desired to cut the material .longitudinally to divide it into more convenient widths .I arrange upon the frame 13 a plurality of sultab y riven lupper and. lower slitting' knives 2,2. -These are so arranged that they 4o eng e and cut in between the double lines of stitchingon the interior strips 3, as indicated at 23 in Fig. 2. This leaves the edges of the bat well supported on all sides.

From-the feed rolls the finishedmaterial-A is carried over an endless conveyer 24 to the desired 'int of delivery. In the present Instance 'have shown it delivered to a suitable swatching machine 25 which automatically folds the strips inv zig-zag piles and severs it into desired lengths, but the de? tails of this are ofno more concernl to thisinvention than is the particular construction..

The feed rolls 12 are preferably hollow and as beforestated, may be steam heatedfor whichv vpurposelthe stubaxles 37 (Fig.

At one end the stub shafts 37 are provided with intermeshing gears 48 and 49 splined thereon,wherebyl the upper rollf'is driven by the` lower roll injan ,opposite direction, through a gear chain. best shown in Figs. 5 and 9, and about to be described.
